But in case you should think (or hope) that the 2013 hurricane season is a bust, Brian McNoldy, a senior researcher at the University of Miami's Rosenstiel School of Marine and Atmospheric Science, has done some potentially sobering math: Writing for The Washington Post's Capital Weather Gang blog, McNoldy points out that while it's somewhat unusual to have no hurricanes this late in the season, it's by no means unprecedented: It happened in 1984, 2001 and 2002.

McNoldy quotes forecaster Phil Klotzbach at Colorado State University as saying that if you crunch the data back to 1960 and add in seasons where there were hurricanes in June and/or July, but none in August, you get four additional years: 1961, 1982, 1988 and 1997.

"Among those, 1961, 1988, and 2001 all ended up being very active and/or destructive hurricane seasons.

"1961 is an especially interesting year, in that August had no tropical cyclones and followed that up with the most active September on record with four major (Category 3-5) hurricanes forming! On the other hand, 1982 and 1997 remained quiet throughout the season."

"Eleven of Colorado State's 18 forecasts have come within three hurricanes of nailing the seasonal total and, on four occasions, they have only missed the cumulative number by one. They hit the mark in 2008. ... Of course, Gray and Klotzbach posted a few wayward forecasts as well: for 1995 (a five-storm underestimate), 2005 (undershot the total by eight) and in 2012 (fell short by six hurricanes)."
